# Microbiome tools for cancer prevention and early detection

**Funder:** European Commission
**Consortium:** Required — minimum 3 entities from 3 EU member states
**Official call:** https://ec.europa.eu/info/funding-tenders/opportunities/portal/screen/opportunities/topic-details/horizon-miss-2026-02-cancer-02
**Last updated:** 7 Sept 2026

## Eligibility & scope

Topic under the EU Cancer Mission (HORIZON-MISS-2026-02-CANCER-02) targeting development and validation of microbiome-based tools for early cancer prediction/prevention using large cohorts, AI risk modelling, and comparison with liquid biopsy tests; successful proposals must join the Mission's 'Prevention and Early Detection' project cluster.

## Summary

This Horizon Europe topic, part of the EU Cancer Mission, funds consortia developing and validating microbiome-based tools for early cancer prediction and prevention, using large patient cohorts and AI risk modelling benchmarked against liquid biopsy tests. It targets multi-partner research teams spanning at least three EU member states rather than individual investigators. Funded projects must join the Mission's 'Prevention and Early Detection' cluster, linking their work to other Cancer Mission projects rather than operating in isolation.

## Who should apply

- Consortia of at least three legal entities from three different EU member states or associated countries
- Research teams combining microbiome science, oncology, and AI/computational risk modelling expertise
- Groups with access to large patient cohorts for prediction and prevention studies
- Applicants able to commit to joining and coordinating within the Cancer Mission's project cluster

## Key dates

- Topic listed under call HORIZON-MISS-2026-02-CANCER-02
- First listed on Grantsby 6 September 2026, verify exact submission deadline on the EU Funding and Tenders portal

## Tips for applicants

- Emphasize cohort scale and data-sharing plans; the topic explicitly calls for large cohorts, so proposals with access to established biobanks or population studies score better.
- Position your microbiome tool against liquid biopsy performance directly in the proposal, the call frames this as a comparative benchmark, not a standalone validation.
- Plan for cluster coordination costs and activities upfront, since joining the 'Prevention and Early Detection' project cluster is mandatory, not optional.
